ProductPPE family protein PPE18
CommentsRv1196, (MTCI364.08), len: 391 aa. PPE18 (alternate gene name: mtb39a). Member of the Mycobacterium tuberculosis PPE family of glycine-rich proteins, highly similar to others e.g. Y07P_MYCTU|Q11031 hypothetical 40.0 kDa protein cy02b10.25c (396 aa), FASTA scores: opt: 2124, E(): 0, (85.1% identity in 397 aa overlap). Note that expression of Rv1196 was demonstrated in lysates by immunodetection (see Dillon et al., 1999).
Functional categoryPe/ppe
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
TranscriptomicsmRNA identified by microarray analysis and down-regulated after 96h of starvation (see Betts et al., 2002). DNA microarrays show higher level of expression in M. tuberculosis H37Rv than in phoP|Rv0757 mutant (See Walters et al., 2006).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene provides a growth advantage for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003).
